If a filter has a surface area of 920 sq/ft and receives a flow of 4,875 gallons per minute, what is the filtration rate in gallons per minute per square foot?

To determine the filtration rate in gallons per minute per square foot, you divide the total flow rate by the surface area of the filter.

In this case, the filter has a surface area of 920 square feet and receives a flow of 4,875 gallons per minute. The calculation is as follows:

Filtration rate = Flow rate / Surface area
Filtration rate = 4,875 gallons per minute / 920 square feet
Filtration rate = 5.2957 gallons per minute per square foot

Rounding this value gives approximately 5.3 gallons per minute per square foot. This calculation illustrates how efficiently the filter can process water based on its size and the volume of water flowing through it. A higher filtration rate indicates a more effective system, as it can handle larger volumes of water relative to its area.
